# Language configuration for Kattis Problem Format
# ================================================
#
# The language configuration consists of a dictionary of languages.
# The keys in the dictionary are lower-case alphanumeric identifiers
# (must match the regular expression "[a-z][a-z0-9]*").  Each language
# is in turn a dictionary which may contain the following six keys.
#
#   name: String, name of the language.
#
#   priority: Integer indicating the tie-breaker priority of this
#             language for language detection.  See "language detection"
#             below.  All languages must have distinct priorities.
#
#   files: String, space-separated glob patterns indicating what files
#          are considered source files.
#
#   shebang: Optional, string, for language detection only.  See
#            semantics under "language detection" below.
#
#   compile: Optional, string, command to compile or syntax-check the
#            source code.
#
#   run: String, command to run a program.
#
#
# Language detection
# ==================
#
# Language detection proceeds as follows:
#
# 1. For each language, a file included in the program is considered
#    to be a source file if its name matches the "files" glob for the
#    language.  If the language specifies a "shebang" entry, the
#    first line of the file *must additionally* match the shebang.
#
# 2. For each language, count how many files in the program are source
#    files for that language.
#
# 3. The language of the program is the one under which the program
#    has the maximum number of source files.  In case of ties, the
#    language that has the highest priority takes precedence.
#
#
# Entry point type
# ================
#
# A language can have three different entry point types, reflecting
# how a program in the language is started:
#
# binary: the compile command produces an executable file
#
# mainfile: name of source code file to pass to interpreter/runtime
#           environment as entry point to the program.
#
# mainclass: similar to mainfile, but at a higher level than a file.
#            Typical (only?) examples are Java and Java-based
#            languages such as Scala.
#
# The entry point type of a language is implicitly specified by using
# one of the four meta-variables {binary}, {mainfile}, {mainclass},
# {Mainclass} defined below.  A language specification *must* use
# exactly one of these four metavariables.
#
#
# Metavariables
# =============
#
# The following metavariables are available for use in the "compile"
# and "run" entries of a language.
#
# {path}: path where the source files are located
#
# {files}: list of all source files
#
# {binary}: arbitrary file name that can be defined by the
#           implementation.
#
# {mainfile}: * if the program consists of a single source file,
#               {mainfile} equals the name of that source file.
#             * if the program contains a source file matching the
#               glob "[mM][aA][iI][nN].*", {mainfile} equals the name
#               of that file (in case of multiple such files,
#               behaviour is undefined).
#             * otherwise, {mainfile} equals the lexicographically
#               smallest source file name
#
# {mainclass}: equals {mainfile} without filename extension.
#
# {Mainclass}: equals {mainclass}, but first letter capitalized.
#
# {memlim}: memory limit
#
